4.1
General
Commissioning the boiler is done for first time use, after a prolonged shut-
down (more than 28 days) or after any event that would require complete
re-installation of the boiler. Commissioning of the boiler allows the user to
review the various settings and checks to be made to start up the boiler in
complete safety.

Starting and stopping the boiler
4.2.1
Commissioning
Caution
Initial commissioning must be done by a qualified professional.
If adapting to another type of gas, e.g. propane, the boiler must
be adjusted before it is switched on.
1. Open the main gas valve.
2. Switch the power on with the boiler's on/off switch.
The boiler starts before the control panel display is active.
3. Set the components (thermostats, control system) so that they request
heat.
4. Check the hydraulic pressure in the installation shown on the control
panel display.
Recommended hydraulic pressure between 0.15 and 0.2 MPa (1.5
and 2.0 bar).
Important
In the event of an error during start-up, a message with the
corresponding code is displayed. The meaning of the error codes
can be found in the error table.
4.2.2
Shutting down the boiler
The boiler must be shut down in order for certain operations to be carried
out on the equipment or its environment.
In other situations, such as an extended absence period we recommend
that Holiday Mode mode is used in order to benefit from the heating pump
anti-blocking function and to protect the installation from frost.
To shut down the boiler:
1. Press the on/off switch.
4.3
Displaying the water pressure on the control panel
1. Highlight the Water Pressure
icon.
The pressure is displayed on the main screen of the control panel.
